Quantitative literacy---the use of mathematics to describe and understand the world---is an essential skill. Physics has an opportunity to contribute to how students develop quantitative literacy, as much of physics curriculum centers on making sense of quantitative models. One facet of quantitative literacy in physics is covariational reasoning:…

Validated conceptual multiple-choice surveys administered before and after instruction in relevant concepts can be useful tools to gauge the effectiveness of curricula and pedagogical strategies. Here we discuss the use of four different validated surveys to investigate student understanding: The Energy and Momentum Conceptual Survey (EMCS), the…

This dissertation investigates the complexities associated with developing expertise in physics problem-solving and the methods for measuring and assessing the skills involved. Problem-solving skills are critical in today's rapidly changing world, and thus, it is important to emphasize them in education. However, lacking precise methods for…

A recent study in our research group found that social comparison concern (SCC) was a medium strength predictor of course grades while controlling for demographic factors and standardized test scores. Additionally, students belonging to underrepresented communities (women and Underrepresented ethnic minorities) had significantly higher SCC than…

Undergraduate physics laboratory curriculum has undergone significant modification in recent decades in response to research and recommendations from educational and professional organizations and stakeholders. These reforms address multiple issues, such as 1) lack of student agency in experimentation, 2) an incomplete framework for student…

A full description of how a STEM protocol model can be an effective and comprehensive implementation of a complete initiative program. A discussion of the factors affecting student comprehension, progress, and cognitive development is made. A historical discussion of STEM policy and programs is included, as is an assessment program in the context…

Having the ability to make informed decisions about health, financial investments, and even the weather are all important to our everyday lives. However, most people receive no formal education on how to read and understand data presented in formats such as data tables and graphs. Research within the field of statistical reasoning demonstrates a…

In recent years, diversity, equity, and inclusion (DEI) have gained increasing importance in the field of physics. Despite efforts to enhance DEI, physics still faces numerous challenges in this area. This dissertation is divided into three main chapters, aiming to investigate the significance of learning-related emotions and physics identity as…

Instructional explanations are an ubiquitous component of classroom instruction, but are relatively neglected in science education when compared to other facets of teaching and learning. The ubiquity of instructional explanations and their potential to stimulate learning in students suggests that they should garner more attention from science…

The relevance of physics is an active line of inquiry within the physics education research (PER) community. Many studies have shown that physics instruction typically negatively impacts students' sense of the relevance of physics to their lives. Irrespective of students' beliefs, physics is communicated as being relevant through policy…

Having discussions and working together in groups with other learners is the indicator of the collaboration aspect of engagement. Collaborative engagement can be fostered through active learning approaches, since they provide more opportunities for interaction among learners. In Process Oriented Guided Inquiry Learning (POGIL) classrooms, small…

Student grades and motivational outcomes in introductory physics courses can influence their retention in science, technology, engineering, and math (STEM) disciplines and future career aspirations. In recent years, many research studies have focused on inequities in calculus-based introductory physics courses, e.g., by investigating gender…

This meta-analysis synthesized research on gender gap in the Force Concept Inventory (FCI). The main goal of the present meta-analysis was to identify the moderator variables that mediate effect size differences. Furthermore, the statistical significance of the average effect sizes was investigated. The inclusion criteria for the meta-analysis…

The effect of class size on student learning has numerous policy implications and has been a major subject of conversation and research for decades. Despite this, few studies have been done on class size in the context of university settings or physics courses. This dissertation helps address that gap in the literature by quantitatively analyzing…

This dissertation examines, in three studies, undergraduate student experiences in social aspects of online learning when conducting remote physics laboratories. The first quantitative, observational study examined introductory students' epistemological, socialization, and help seeking views (N=998). Parametric and nonparametric tests indicated no…
